58m of Filament and 39 Hours...

Learning Challenge: As part of the student projects for Technology for Y7/Y8 students at Auroa Primary School in New Zealand students had a design option for the final block of time in class.  Students had to plan, create manufacture a free design option - the student in this case choose to create a Kitchen Utility Holder, however the dimensions of the object, which were approximately 30cm cubed meant this was the single biggest print to date.

Background:  Auroa Primary School has put online its digital learning for the use of 3D Printers.  You can view that by clicking on the link here.  As mentioned above this design came in the final part of the 3D Print Design Process, however it was significant that this was the largest single print attempted thus far.

Task: A free design task for students, however it was not an 'open' task as students had to design, create and follow a process.

Level of Difficulty: Moderate - the design was the creation of the students.  In this case the name of the student was cut into the design.

Issues: The inserts into some of the utility holder were vertical, this meant that the primary one worked well, however the angle on the other ones should have been tested with various kitchen items to ensure that they would work with a variety of items.   Wooden spoons for instance would sit well in the main well, however the angle of the outside holders had meant that would not work.

Timeframe: This print took 39 hours to complete on a regular setting.  It wasn't clear prior to the print whether or not it would be achievable.  Given the time that was projected being so long the concern was that the print would not smoothly print at some point early in the piece preventing the print from completing.  As it turned out this was unfounded.  It printed perfectly.

Size: the completed project was 30cm wide, 30cm long and 25cm high.   The print used 58m of filament.

Process: Paper design, converted and created in Tinkercad.  Converted from Tinkercad into Cura and then downloaded for 3D Printing.   The student had not apparently intended the design to be as big as it was.

Further Reading: Auroa Primary School's Technology Program is now available online.  It includes the entire teaching process, details about student projects and examples.
